Alpine SPC-R100-DU Premium 12 cm (4.8-inch) radial speaker system for Fiat Ducato (250, 290), Peugeot Boxer, Opel Movano, and Citroën Jumper. The 10 cm radial speaker system SPC-R100-DU for the Fiat Ducato 3 and similar vehicles significantly enhances the sound quality, especially in the mid-range frequencies. This is particularly important as it falls within the range that is well heard by the human ear. The original door speakers in the Ducato are positioned at knee height for the driver and passenger, which prevents them from creating a good soundstage. By installing the Alpine radial speakers, which can reproduce the entire frequency range, the soundstage is elevated to the dashboard. This results in voices and fine details being reproduced much more clearly, greatly improving the listening experience. This advantage is especially noticeable when playing podcasts, audiobooks, or radio programs. Installation is straightforward. The speaker wires are connected to the original tweeter and plugged into the Alpine speakers using an adapter. The Alpine speakers feature a special design with "convex" speaker membranes, which offers two benefits: first, the speaker has no mounting depth (no cutout in the dashboard is required), and second, the speaker radiates perfectly in 360 degrees around the dashboard, creating an excellent sound image.
